lay your material flat
and locate the point you would like to use as the center of your diamond.
Fold your material in
half over your selected point.
Fold the material a second
time, again over your center point, but this time, make your fold perpendicular
to the previous fold. Your material should be 1/4 the size it was
originally.
Now "fan" your material
longwise from the center point out.
When it opens, the folds
should look like this
Next, apply your
dye. I always use:
Procion(TM) MX Fiber Reactive Dyes from Dharma
Trading. I use sponge brushes. The picture I have shown
is a side view, but I actually apply the dye along the folds and allow
it to soak toward the middle. Be careful about how much dye you apply.
It must penetrate four (in my example of a plain piece of material) or
eight (in the case of a T-shirt) layers of material; don't soak the material
to the point of dripping ~ it is wasteful, messy, and the end result will
not be nearly as pleasing (unless that is the effect you are pursuing or
you are using dyes or dye techniques that require dipping or dunking.)
The end result should
be something like this.
